摘要
本文对微型燃气轮机并网整流与升压控制回路进行了设计与仿真。整流部分(Rectifier system)选用电压型PWM整流器(VSR),所搭建模型主要包括输入滤波电感(Reactor)、整流桥(Three-Level Bridge Rectifier)、整流控制器(Rectifier Controller)和直流滤波电容(C1, C2)。本次研究课题的斩波电路选用的是升压Boost斩波电路,将电压调节器用作外环控制,电流内环则根据id*、iq*的值来控制电流,从而实现对交流侧电流的快速调节作用。Boost Controller模块主要是通过产生合适的控制脉冲信号来控制可控开关Mosfet的通断,最终实现调节输出电压的目的。仿真结果表明本文设计的整流电路与升压控制回路输出电压波形稳定性优良。
In this paper, the design and simulation of the micro-turbine grid-connected rectification and boost control circuit are carried out. Rectifier system selected voltage-type PWM rectifier (VSR), the proposed model includes input filter inductors (Reactor), rectifier bridge (Three-Level Bridge Rectifier), rectifier controller and DC filter capacitor (C1, C2). The chopping circuit of this research topic is the step-up Boost chopper circuit, the voltage regulator for the outer ring control, and current inner ring can be based on id*, iq* value to control the current, in order to achieve the ra- pid adjustment of the AC side of the current role. Boost Controller module is mainly through the generation of appropriate control pulse signal, thus controlling the control switch Mosfet off, and ultimately achieving the purpose of adjusting the output voltage. The simulation results show that the design of the rectifier circuit and the boost control circuit output voltage waveform stability is excellent.
